Effects of SA on transcripts abundance and plant growth. A, Transcript abundance; whole shoot samples were harvested 1, 8, and 24 h after spraying, which was performed halfway through the light period. Semiquantitative RT-PCR was performed on 3-week-old tobacco plants sprayed with 10 μm or 1 mm SA and then exposed to an extended photoperiod (24 h at 250 μmol m–2 s–1). Actin was used as the internal control. B, Plant growth; phenotype of SA-treated and -untreated plants showing seedlings before treatment (a) and 1 week after the treatment (b). This experiment was repeated three times and similar results were obtained.
